Some neo-clerodane diterpenoids isolated from plants belonging to the Teucrium genus and possessing different functionalities at the C-6, C-7 and C-19 positions were heated above their melting points without any solvent. This treatment produced good yields of different rearranged products, which are useful intermediates for the synthesis of other natural neo-clerodane derivatives.

Abstract Three new neo-clerodanediterpenoids, teulepicin, 19-acetylteulepicin and teulepicephin, have been isolated, together with the previously known flavone cirsiliol from the aerial parts of Teucrium lepicephalum . The structures of the diterpenoids were established by chemical and spectroscopic means and by correlation with known substances. In addition, 19-acetylteulepicin and the already known
